Although Chris Brown is yet to collaborate with Bruno Mars, he has remixed Beyonce’s “Jealous.” He’s also worked with Rihanna in the past on “Nobody’s Business,” “Birthday Cake (Remix),” and more.

Some took issue with Brown’s mention of Rihanna, since the tweet lands on the nine-year anniversary of his 2009 assault of his former girlfriend. Last year, he opened up about the life-altering incident in his Welcome to My Life documentary. “A lot of the times, I look back at that picture and I’m like, ‘That’s not me, bro.’ I hate it to this day,” he said. “That’s gonna haunt me forever.”
